Possible Issue- Insufficient free space

Delete content manually

If there isn't enough space to download and install an update, iOS tries to make more space. It temporarily removes some downloadable parts of installed apps. You shouldn't need to remove or relocate any content. But in some cases, it's necessary to manually delete some content.

In the Usage Settings menu, you can see how much space your apps use and delete the ones you don't need. You can download your purchased apps or other content again later. Follow these steps:

Tap Settings > General > Storage & iCloud Usage > Manage Storage.

Select any app to see how much space it uses, and tap Delete App to remove it. Some apps, such as Music and Videos, let you delete parts of their documents and data.

Manage space with recommendations in iOS 11 and later

In the iPhone Storage menu in iOS 11, you can manage the storage on your device. You can see which apps take up the most space, or you can delete or offload an app or some of its content. You can download your purchased apps or other content again later.

To see the iPhone Storage menu, tap Settings > General > iPhone Storage. In the Recommendations section, you can see tips for how to save space and how to offload or delete apps and content you don't need.
